Systems and methods to prevent incorporation of a used integrated circuit chip into a product

A system comprising:

• a product;
• and
• a printed circuit board incorporated into said product, said printed circuit board comprising multiple integrated circuit chips with one of said multiple integrated circuit chips being a supervising microprocessor chip electrically connected to all others of said multiple integrated circuit chips,
• said multiple integrated circuit chips comprising corresponding sets of programmable bits,
• said supervising microprocessor chip further comprising an additional set of programmable bits programmed with an identifier for said printed circuit board, and
• said supervising microprocessor chip verifying validity of all of said multiple integrated circuit chips on said printed circuit board by performing the following, for each specific integrated circuit chip on said printed circuit board:
• reading a corresponding set of programmable bits on said specific integrated circuit chip;
• and,
• determining whether said corresponding set of programmable bits is programmed to match a specific section of said identifier, said specific section being associated with said specific integrated circuit chip.

A method comprising:

• assembling a product comprising a printed circuit board,
• said printed circuit board comprising multiple integrated circuit chips, and
• said multiple integrated circuit chips comprising corresponding sets of programmable bits;
• and,
• verifying validity of all of said multiple integrated circuit chips on said printed circuit board by performing the following, for each specific integrated circuit chip on said printed circuit board:
• reading a corresponding set of programmable bits on said specific integrated circuit chip;
• and,
• determining whether said corresponding set of programmable bits has been programmed to match a specific section of an identifier of said printed circuit board.
